IP Version 6 (IPv6) Support
The device functions as an IPv6-compliant host, as well as an IPv4 host (also
known as dual stack). This enables device operation in a pure IPv6 network as
well as in a combined IPv4/IPv6 network.
For more information, see
IPv6 Addressing .
Head of Line Blocking Prevention
Head of Line (HOL) blocking results in traffic delays and frame loss caused
by traffic competing for the same egress port resources. To prevent HOL
blocking, the device queues packets. The packets at the head of the queue are
forwarded before packets at the end of the queue.
Back Pressure Support
On half-duplex links, the receiving port prevents buffer overflows by
occupying the link so that it is unavailable for additional traffic.
For more information, see
Back Pressure .
Virtual Cable Testing (VCT)
VCT detects and reports copper link cabling faults, such as open cables and
cable shorts.
For more information, see
Diagnostics .
Auto-Negotiation
Auto-negotiation enables the device to advertise modes of operation. The
auto-negotiation function enables an exchange of information between two
devices that share a point-to-point link segment, and automatically
configures both devices to take maximum advantage of their transmission
capabilities.
